The Dune series by Frank Herbert. All of them, some were better than others, but I liked them all.

The Once and Future King by T. H. White

Don Quixote de La Mancha by Miguel de Cervantes both parts (the sequel is actually better than the original)

Any short story by Enrique Anderson-Imbert (an Argentinian author who makes me cry with laughter)

The Hobbit and The Lord of the Rings The movies were great, but the books are better as always.

And you are going to laugh, but I love the Tarzan books. Reading about a half-naked dominant male who hunts the wild creatures of the jungle with nothing but a knife and his bare hands and speaks French and English to boot sets me on fire. <sigh>
hmm..... I wonder how Woodsman would look in a loincloth? <pulls out her sewing machine>
